If you reused a role from a past character that I rated, then I rate it 0 since you've been rated for it before. You can always add addendums, additional journal entries, new outlooks, dialogues, etc. to fill the role-xp void since those wouldn't be duplicates.
In your case, you've been rated. You can see what you got using 'score exp'. If you're itching for more, add some more roles .
